I've chaged your code slightly and added comments to help
explain -



<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="initApplication();">

<mx:Script>

<![CDATA[

import mx.rpc.events.ResultEvent;

import mx.controls.Alert;

import mx.collections.ArrayCollection;





private function initApplication():void

{

// myService is the RemoteObject tag reference id

// once the application creation is complete call
myService.sayHelloQuery() method

this.myService.sayHelloQuery();

}





[Bindable]

public var qResult:ArrayCollection;





}

public function handleQueryResult(event:ResultEvent):void{

qResult=event.result as ArrayCollection;

}
